There is a very convenient example in modern technology. The old motion picture film is actually made up of many reversal films; the first picture film has no connection whatsoever with the second picture film, but due to the speed at which they are rolled out (twenty-four films per second), we do not notice where one picture ends and the next begins. We mistakenly think when a person in an image is walking and talking, it is one continuous motion; we do not expect the connecting images to be formed by many separate films. An illusion is produced because our eye cannot perceive matter of a subtle nature. For scientists and philosophers, this logic should be easy to follow.
Thus, Buddhism believes all phenomena which arise and cease due to causes and conditions are like a dream, like magic, like a water bubble, like shadow. They are all unreal and illusory.
